Do we believe in the Trinity because we have faith in the scriptures and find revelation of the doctrine there in the text or because we have faith in the creeds and traditions that speak of God as trinitarian?
I would quibble with (inter alia) "faith in..." here, but the answer is YES!...but ultimately the former. Remember Thomas, ST I q 1 a 8 ad 2: necessity from theological argument is tied up with holy Scripture, and only secondarily with other writings.
